Hot Shot’s Secret® Expands Product Lineup with Diesel Injector Flush

June 26, 2025

Hot Shot’s Secret®, the fastest growing diesel additive brand in America, adds Diesel Injector Flush™ to their lineup of diesel additive solutions. Diesel Injector Flush is a concentrated flush that quickly and safely cleans diesel fuel injectors, restoring out of spec injector balance rates.  

The innovation behind Diesel Injector Flush comes from identifying the needs of customers and fleets by working alongside them and reviewing OEM technical service bulletins. Diesel Injector Flush is formulated with a high cetane base, along with cleaning & lubricity additives to ensure safe engine operation during the cleaning process. The root of the issue stems from modern engines that require ultra-low sulfur diesel and higher fuel pressures, making them more prone to internal diesel injector deposits (IDIDs). IDIDs cause rough idle, reduced fuel economy, and diagnostic trouble codes such as P0263–P0278 or P1263–P1278. 

Diesel Injector Flush is used in combination with other products in the Hot Shot’s Secret lineup: “If you think of your diesel fuel system like dental care, Everyday Diesel Treatment® (EDT) is like brushing your teeth; Diesel Extreme® is your regular dental cleaning, and Diesel Injector Flush is the oral surgeon. You’ll use it less frequently, but it’s critical to keep your injectors operating efficiently. In our testing the flush restored injector performance without replacement of an expensive injector and lots of shop time,” says Hot Shot’s Secret Brand Manager, Josh Steinmetz. The formula and treatment method provides an even deeper cleaning than Diesel Extreme and works by deeply cleaning internal and external injector deposits, restoring spray pattern, timing, and balance rates. 

Diesel Injector Flush is suggested to be used during a fuel filter change as preventative maintenance, or when injectors issues are present. These issues include inconsistent injector contribution rates, the appearance of codes, or declining drivability. It helps reclaim lost fuel economy, power, and throttle response—often eliminating the need for costly injector replacement. The product can be used by filling the fuel filter or tapping into the fuel system and running the engine on the product. Regular usage has shown decreased DPF regeneration cycles, another benefit of the product.  

Diesel Injector Flush is available in two sizes to suit a range of engine needs: a 32 oz. bottle, ideal for smaller engines and pickups, and a 1-gallon option, recommended for engines over 8 liters, including medium-duty trucks, semis tractors, and equipment. The 32 oz. bottle is currently available at HotShotSecret.com. Both sizes are available nationwide at a local Hot Shot’s Secret dealer near you.
